In addition, in certain embodiments, the vehicle 100 includes a front axle 114 and a rear axle 116, and the front windshield 104 is disposed in front of the front axle 114. Also in various embodiments, the shock cap assembly 102 is also installed directly underneath the front windshield 104.
It is noted that the particular configuration and installation of the shock cap assembly 102 as described herein is particular useful for, but is not limited to, configurations in which a base of the windshield 104 extends in front of the front axle 114 and (along with related structure and related interior components) covers the shock towers from above. However, in certain embodiments, the windshield 104 may not be disposed in front of the front axle 114 and/or may not cover the shock towers from above. In such embodiments, the configuration and installation of the shock cap assembly 102 as described herein may still be particularly useful, for example in which a vehicle floor, occupant compartment, and/or other components may preclude access from above.
In certain embodiments, the vehicle 100 comprises an automobile. In various embodiments, the vehicle 100 may be any one of a number of different types of automobiles, such as, for example, a sedan, a wagon, a truck, or a sport utility vehicle (SUV), and may be two-wheel drive (2WD) (i.e., rear-wheel drive or front-wheel drive), four-wheel drive (4WD) or all-wheel drive (AWD), and/or various other types of vehicles in certain embodiments. In certain embodiments, the vehicle 100 may also comprise one or more other types of vehicles. In addition, in various embodiments, it will also be appreciated that the vehicle 100 may comprise any number of other types of mobile platforms.
In the depicted embodiment, the body 110 of the vehicle 100 substantially encloses other components of the vehicle 100. Also in the depicted embodiment, the vehicle 100 includes the above-referenced axles 114, 116 and front wheels 112, as well as rear wheels 113. The wheels 112, 113 are each rotationally coupled to a respective one or more of the axles 114, 116 near a respective corner of the body 110 to facilitate movement of the vehicle 100. In one embodiment, the vehicle 100 includes four wheels 112, 113 (namely, two front wheels 112 and two rear wheels 113), although this may vary in other embodiments (for example for trucks and certain other vehicles).
In various embodiments, the drive system 106 drives the wheels 112, 113. The drive system 106 preferably comprises a propulsion system. In certain exemplary embodiments, the drive system 106 comprises an internal combustion engine and/or an electric motor/generator. In certain embodiments, the drive system 106 may vary, and/or two or more drive systems 106 may be used. By way of example, the vehicle 100 may also incorporate any one of, or combination of, a number of different types of propulsion systems, such as, for example, a gasoline or diesel fueled combustion engine, a “flex fuel vehicle” (FFV) engine (i.e., using a mixture of gasoline and alcohol), a gaseous compound (e.g., hydrogen and/or natural gas) fueled engine, a combustion/electric motor hybrid engine, and an electric motor.
In various embodiments the suspension system 103 supports road handling and ride quality for the vehicle 100. In various embodiments, the suspension system 103 comprises a number of components, such as the shock cap assembly 102 as well as tires, springs, and the like that connect the body 110 of the vehicle 100 to the wheels 112, 113, that allow relative motion therebetween, and that support both road handling and ride quality.

In various embodiments, during step 510, the installing of the shock cap assembly 102 into the body 110 of the vehicle is performed via access through a front wheel well of the vehicle (e.g., wheel well 111 of
In various embodiments, following step 510, other components are assembled (e.g., installation of suspension control arms, wheels, and tires) at 512. Also in various embodiments, the process 500 thereafter ends at 514, when the manufacturing of the vehicle 100 is complete.

As shown in
In various embodiments, the torsional hoop structure 940 is formed by the integrated cross car beam (which is part of the windshield base structure) at the top, the chassis at the bottom, and the front compartment rails on the sides. Also in various embodiments, the shock cap assembly joins vertical members (namely, front compartment rails) to the upper horizontal member (namely, the integrated cross beam).
Also as depicted in
Further, with reference to
As depicted in
In various embodiments, the support structure provided by the integrated brace 1000 of this configuration provides additional structural support for the windshield 104, which may be needed as a result of the windshield being cantilevered due to its placement forward of the front axle 114 of the vehicle 100. In addition, this configuration with the integrated brace 1000 (including the hoop structure with the cross-support shock tower brackets 812) further provides structural continuity between the shock cap assembly 102 and the windshield base structure 802, without requiring redundant structure for cross-support. In short, in an exemplary embodiment, integral support is provided as the shock cap assembly 102 provides structural support for the windshield 104 (e.g., via the brackets 812 of
In various embodiments, the torsional hoop structure is formed by the integrated cross car beam 1000 (which is part of the windshield base structure) at the top, the chassis 804 at the bottom, and the front compartment rails 810 on the sides. Also in various embodiments, in so doing, the shock cap assembly 102 joins vertical members (namely, front compartment rails 810) to the upper horizontal member (namely, the integrated cross beam 1000). In various embodiments, the torsional hoop structure not only provides structural support for the windshield 104, but also contributes to the overall body rigidity for the vehicle 100 and manages loads from the shocks.
In addition, as noted above, in certain embodiments mid beam 806 may also be included, for example as a secondary member for various purposes, such as attachment of other components, as well as providing some structural support to the vehicle 100.
Accordingly, systems, methods, and vehicle are provided for shock cap assemblies installed in vehicles. In various embodiments, the shock cap assemblies are sub-assembled prior to installation in the vehicle. Also in various embodiments, the configuration of the shock cap assemblies as installed in the vehicle enables the shock cap assembly to be accessed from the side of the vehicle, via a vehicle wheel well, for installation, service, repair, and removal. This is particularly useful for, but is not limited to, configurations in which the windshield covers the shock towers from above, and/or in which a vehicle floor, occupant compartment, and/or other vehicle components may preclude access from above.
In addition, in various embodiments, the installed shock cap assembly includes an integrated beam connected to the shock tower to complete a torsional hoop structure that results in an integrated support system for the shock cap assembly and the windshield support structure, by which the windshield base structure and shock cap assembly mutually support one another in an integrated manner. In addition, in various embodiments, the installation of the shock cap assembly in the vehicle utilized with an integrated cross-vehicle brace in the windshield support structure provides structural continuity without the need for a separate structure element, such as a separate tower-to-tower brace. In various embodiments, the torsional hoop structure also contributes to overall body rigidity and managing loads from shocks of the vehicle 100.
It will be appreciated that the systems, vehicles, methods, applications, and implementations may vary from those depicted in the Figures and described herein. For example, in various embodiments, the vehicle 100, the shock cap assembly 102, the windshield 104, and/or various components thereof, and/or other components may differ from those depicted in
While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the disclosure in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing the exemplary embodiment or exemplary embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the scope of the disclosure as set forth in the appended claims and the legal equivalents thereof
